Author Raynor Winn experienced a week like no other back in 2013 - and it inspired the hit film starring Gillian Anderson and Jason Isaacs.

In the space of seven days, she and her husband Moth lost their family home, and then Moth was diagnosed with a rare terminal degenerative brain disease and given two years to live.  

Homeless and facing an uncertain future together, Raynor and Moth left on a 630 mile trek along the South West Coast path and made the trail their home. 

That journey inspired Raynor's book - The Salt Path.

"Many books get optioned, but they rarely make it to film. So I didn't expect the film to be made, to be honest. So when I realised it was actually happening - I think my main concern was how they could capture the story."
